I think by "hifi" they may mean "as good as the $5 1800W PMPO computer speakers used in many multimedia computers.

There is just not enough information available at the website to make me believe otherwise. There is just some marketing mumbo-jumbo about how sideways sound inside your monitor is better than two completely separate speakers beside your monitor. There really isn't any actual information there.

For example, in the FAQ:

Quote:

What is the frequency response of an Edge Motion™ speaker system and how loud can it play?
The answer to both of these questions will depend on the specific application and how the speaker system is implemented. An Edge Motion™ speaker system can be designed to reproduce full, natural sound at high listening levels. However, based on display size and the intended use, some applications will have less demanding requirements for how low and loud the speaker system plays.

Translation:
Q. What is the frequency response of the Edge Motion?
A. It sounds good and loud, but not that loud, and maybe not that good.

Looking at it from a non-hifi perspective, yes Badman is right, it is cool tech, and definitely has a useful application.
